Development of a Robust Drill Head Integrated Cross Bore Warning System for Horizontal Directional Drilling

Description :  

The objective of the investigators of this research is to reduce the risk of unintentional damage to existing utilities during Horizontal Directional Drilling (HDD). Current technology designed to detect existing utilities are not effective in sensing small non-metallic structures, including vitrified clay and Orangeburg pipes. In order to prevent damage in HDD operations, the investigators seek to examine three sensor types: a microwave based EM sensor, a capacitive sensor and an impact detection sensor in order to develop a drill head-mounted cross bore warning system capable of alerting HDD operators in real time. In addition to numerical modeling and laboratory experiments, a field demonstration would be conducted on the proposed sensor. In developing a drill head-mounted sensor, operators could be alerted to existing utilities within 20 centimeters of the drill head.
